SHINGLE-BINDING DEVICE.

Specification of Letters Patent.

Patented May 22, 191'7.

Application filed February 19, 1916. Serial No. 79,422.

To all whom it may concern:

Be it known that I, HUGH MoLEAr 'a subject of the King of Great Britain, and resident of the town of Bathurst, in the Province of New Brunswick, in the D0- minion of Canada, have invented certain.

new and useful Improvements in Shingle Binding Devices; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in shingle binding devices as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel construction and arrangement of parts whereby the bundle in loose form is gripped between the binding strips and through the combined action of cam and crank operated by a single lever forced into position for fastening.

The objects of the invention are to devise a simple means of making up bundles of shingles quickly without the use of skilled labor, to bind the shingles very securely and neatly and generally to provide a cheap, serviceable and durable shingle binder.

In the drawings, Figure 1 is a side elevation of the binder.

Fig. 2 is a cross sectional view on'the line A-B in Fig. 1.

Fig. 3 is a sectional detail of a pressure bar, showing a cam and cam plate.

Fig. 4 is a perspective View of the binding mechanism removed from the frame.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, the frame 1 is preferably made of wood with the rigid back 2 standing on the cross beam 3, the latter being supported on and rigidly secured to the longitudinal beams 4 and 5, said outer beams 4 sloping from the deeper ends 6 to the narrower ends 7, where the front cross beam 8 is rigidly secured and also the hinged face board 9 to said cross beam 8.

The shaft 10 is journaled in the beams 4 and 5 and between said beams at each side of the frame has the cams llfixedly mounted thereon.

The cam plates 12 are secured between said beams 4 and 5 on the pivot pins 13 and reach rearwardly over the cams 11 and at each rotation of the shaft 10 are bodily lifted against the lower binding strip of the bundle of shingles.

The cranks 14 are fixedly mounted on said shaft 10 outside of the frame 1 and have the curved links 15 pivotally secured thereto.

The shaft 10 is operated by the lever 16 rigidly securedto one end of said shaft.

The pressure bars 17 are formed with the lower legs 18 straddling the shaft 10 between the beams 4 and 5 at each side of the frame, and the upper legs 19, the latter terminating in the feet 20 for gripping the upper binding strip of the bundle of shingles.

A pivot pin 21 extends outwardly from each of the pressure bars 17 intermediate of the height thereof, said pins 21 projecting through the guide plates 22 in the vertical slots 23.

The guide plates 22 are rigidly secured to the beams 4 and the pins 21 are pivotally secured to the links 15 thus operatively connecting the shaft 10 to the pressure bars 17.

The bridge pieces 24 between the beams 4 and 5 at each side of the frame ordinarily support the cam plate 12.

The operation of the device is as follows The shingles are piled in the frame between the back 2 and the face 9, the thinner ends of the shingles overlapping as customary. The bottom binding strip is already in place and fastened to the iron bands and the latter extend upwardly and are adapted to be bent inwardly over the upper binding strip between the upper legs 19 and feet 20, which in binding position are gripping said upper binding strlp.

The rotation of the shaft 10 by means of the lever 16 lifts the plates 12 against the lower binding strip and coincidently the pressure bars are drawn downwardly by means of the cranks and connecting links and as the said feet 20 at the upper ends of said pressure bars are gripping the upper binding strips, naturally the thinner overlapping ends of the shingles are squeezed between the said binding strips and as soon as the bundle is pressed sufficiently the iron bands are nailed to the upper strip and the bundle is then finished.

What I claim is In a shingle binding device, a frame having a rigid'back and hinged face and base formed of longitudinal and cross beams, said longitudinal beams being formed of inner and outer pairs, guide plates having vertical slots and secured to said outer beams, a shaft journaled in said frame, pressure bars havf'5f ing lower legs straddling said shaft and gripping feet at the top ends of the upper legs and pivot pins projecting through said vertical slots, cranks mounted on said shafts, curved links connecting said cranks and said 10 pivot pins, cams mounted on said shaft, cam

plates pivotally secured at one end and reaching over said cams and lifted thereby, and a lever secured to one end of said shaft and projecting upwardly therefrom.
